4 Claims. (01. 189- 19) welded to each of the members a with respectfto each other, and

This invention relates to the construction of towers, masts and analogous structures.

An object of the invention is' the provision of improvementswhereby assembled components of' a structure of the indicated character may be rigidly connected together quickly, easilyand' economically. Q

A further object of theinvention is'the provision of improvements whereby structural elements may be rigidly connected together in tower or mast forming relationship by the use of material such as cable or stout wire which binds or secures the structural elements to each other and also serves as trussing means for said elements.

With the foregoing, other objects of the inven tion willappear when the following specification is read in conjunction with the accompanying drawing, in whichi Fig. 1 is a fragmentary side elevational view of a tower or mast embodying the features of the invention.

Fig. 2 is a horizontal sectional the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary side elevational view of one of the joints and counterparts thereof, portions being shown in section.

Fig. 4 is a view of the joint and counterparts shown in Fig. 3 looking at the same from a different angle.

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 3 and showing the cable or wire clamp open.

Fig. 6 isa view similar to Fig. 5, but showing the clamp closed on the cable or wire.

Fig. 7 is a side elevational view showing certain modifications, portions being shown in vertical section.

In the drawing, there are shown structural element Ill which constitute upright leg sections or components of a tower, mast, or analogous structures. The elements l0 may be of any suitable material such as metal or wood. They may be solid or tubular and of any preferred length and cross-sectional shape and size. In the present instance the elements [0 are in the form of crosssectionally round metal tubing of uniform length and cross-sectional size.

Use i made of groups of tubular splices or coupling members H. The number of such groups depends upon the height of the structure desired. The members ll of each group are rigidly connected together in spaced relation by cross-stays or bars 12 and branch tubular coupling members l3. A pair of the members I3 is view taken on member l3 at a right'angle to the longitudinal axis of the memher-1 2 In 'thepresent instance there are three members H in each group because the'tower or mast is triangular in horizontal section. Hence, three st'ays or ba'rs 12' are used' for each group of members II. The oppositeends of eachstay or bar 'IZare received in' the members I 3,'respectively, at each side of the assemblage. Bolts :and nuts M secure the stays or bars l2 to the members l3.

The sections ID of each leg of the tower or mast are arranged vertically in end-to-end relation, and a pair of the sections I 0 i accommodated by each of the coupling members H. The opposing ends of each pair of the leg sections ID are inserted into the opposite ends respectively of the related member I I. The opposing ends of the sections l0 abut each other. Bolts l5 extend transversely through each member II and the sections l0. Each bolt ha a fixed nut l6 and a removable nut I I. Each of the nuts I6 has a round head or cap i8 welded or otherwise secured thereto. The bolts l5 and their heads l8 constitute fixed studs or pegs on the coupling members II for a purpose to appear.

After the leg sections In and interconnected coupling members H are assembled and bolted as described and illustrated in Fig. 1, cable or stout wire stock I9 is used to brace or truss the parts to give the structure added strength and rigidity.

A single wire [9 may brace all sides of the tower by starting it at the bottom corner of the tower and zigzagging it up to the top, horizontally across and down to the bottom to brace one side of the tower and repeating this operation for each remaining side of the tower. When zigzagging the wire up a side of the tower it is secured to the lugs H! by passing it over the upper lug of a pair then down and across the bottom of a lower lug of a pair then diagonally across to a pair of lugs I 8 on an opposite leg of the tower where it is passed over the upper lug of a pair down and across the bottom of the lower lug of the pair and so on. When the wire is being zigzagged down a side of the tower it is secured to a pair of lugs by first being passed under the bottom lug of a pair then upwardly then over the top lug of a pair then diagonally across to a pair of lugs on an opposite leg where the operation is repeated. The tower may also be braced by a separate wire for each side, which wire is zigzagged up and down a side to provide the bracing.

l2 at an angle up or down only once. No matter how many wires are used they are secured to lugs IS in the same manner.

If desired, suitable clamps 20 may be used to take up any possible slack in the cable or wire. One of the clamps 20 is applied to the wrappings of the cable or wire on each pair of studs or heads l8 as shown in Figs. 3-6. In Fig. 5, the clamp 20 is open, and in Fig. 6 the clampfis closed into. clamping engagement with portions of'the cable or wire extending in parallel relation between the studs Hi. The use of the clamps 20 is optional.

The cable or wire stock applied in the manner described servesadequately to not only braceor,

truss the assembled parts, but also to connect them together and I5. case, the heads l8 will be welded or otherwise directly secured as at 2| shown in Fig. '7. Each coupling member II will have a transverse partition 22 or lugs on the inside thereof to serve as an abutment meansv for the opposing ends of theleg sections II inserted into the member I I. Thecable or wire draws the groups of coupling members H. at the top and bottom of-the structure toward each other in a lengthwise direction and atthe same time draws on the members I l in a transverse or hori' without the use of the bolts H1 Hence, they may be omitted. In such to the members H, as

zontal direction, thereby keeping the leg sections Ill and stays or rods l2 in their coupling members and so forming a rigid braced and trussed tower or mast.

I claim: 1

1. A structure of the character described com prising spaced uprights composed of sections, tubular splices, means rigidly connecting the splices in spaced relation, the opposing ends of two of thesections extending into each of said tubular splices and connected thereto, each splice having a pair of studs thereon, thestuds of each pair disposed near the opposite ends respectively I ofthe splice, and a continuous wire looped in engagement with one pair of studs after another and alternating from one upright to the other upri'ghtfor the purpose of retaining the sections assembled and providing diagonal trussing.

2. A structure as set forth in claim 1, and means to keep the wire taut.

3. A- structure as set forth in claim 1, wherein said studs consist of fastening elements extending through the splices and upright sections and also serve to connect the splices to the sections. i.v A structure as set forth in claim 1, wherein each of said tubular splices has an abutment between the ends against which the ends of the respective sections abut.
